Concerns Based Adoption Model (CBAM)
This model describes the intellectual and emotional stages a person goes through when implementing or learning something new. Understanding these stages helps the person understand what is normal and natural about the hard work of changing. We use the CBAM model to help us plan and differentiate professional development for educators learning about and implementing work related to our Mission – including the Problem Solving Task (PST) processes.
